The Fisheye lens captures approximately a 180 Degree field-of-view and produces some striking images.
The Wide-Angle lens is great for when you need that extra field of view, approximately double that of the normal IPhone.
The Macro lens applies roughly a 10X multiplier and allows you to focus the iPhone within 12-15mm of the subject. The Macro lens is cleverly concealed within the olloclip and can be accessed by unscrewing the Wide-Angle lens that is normally attached to it.
The olloclip ships with a carrying bag made from a microfiber material that doubles as a lens cleaner and conveniently holds the supplied-lens caps or the Wide-Angle lens when removed for Macro shots.
